Except for royal lineages, Bhutanese names do not include a family name. Instead two traditional auspicious names are chosen at birth by the local lama or by the parents or grandparents of the child. First names generally give no indication if the person is male or female; in some cases the second name may be helpful in that regard.
As there is a limited constellation of acceptable names to choose from, inevitably many people share the same combination of first and second names. To resolve the ambiguity an informal nicknaming system comes into play which recognizes where a person is from. If a certain "Chong Kinley" is from Chozom village in the Paro valley, she is called "Paro Kinley" when she is travelling outside the valley. In Paro valley itself she is identified by the name of her village, thus "Chong Kinley Chozom". Surprisingly, multiple children in a small hamlet of a few houses may have exactly the same name, reflecting the inspiration of the local lama. In this case, she is identified by the name of the house she was born in, thus "Chemsarpo" Kinley.
